vsock/test: add a final full barrier after run all tests
[ Upstream commit c39a6a277e0e67ffff6a8efcbbf7e7e23ce9e38c ]
If the last test fails, the other side still completes correctly,
which could lead to false positives.
Let's add a final barrier that ensures that the last test has finished
correctly on both sides, but also that the two sides agree on the
number of tests to be performed.
Fixes: 2f65b44e199c ("VSOCK: add full barrier between test cases")
